EJECT ING MECHANISM FOR BREAKDOWN GUNS.

SPECIFICATION forming part of Letters Patent No. 538,810, dated May 7,1895. Application filed January 2,1895. Serial No. 533,539- No model.)

To all whom, it may concern:

Be it known that we, HENRY ALFRED ALEX- ANDER THORN (trading as CHARLESLANCAS- TER) and WILLIAM BODIN, subjects of the Queen of Great Britain,residing at London, England, have invented new and useful Improvementsin Drop-Down Guns or Small- Arms, of which the following is aspecification.

Our invention relates to a means of holding the tripping rod working inthe body of the action in its. forward state for the purpose of trippingejecting mechanism carried in the foreend, such holding forward notbeing dependent on the hammer being at cook or at bearer at the momentof tripping. By this means we are able to regulate the tripping of theejector mechanism to any moment during the opening of the gun. To effectthis we pivot in the frame of the action a spring looking lever soformed as to engage at one end with the lump of the gun and at the otherwith the tripping rod. On the firing of the gun the rod is carriedforward in the usual manner and allows the one end of the pivoted leverto engage with it by means of an operating spring and hold it rigid onthe opening of the gun. On closing the gun the lump coming in contactwith the other end of the pivoted lever, rotates it out of contact withthe rod and allows the tripping rod to be re turned.

To enable our invention to be fully understood we will describe the sameby reference to the accompanying drawings, in which- Figure l is a view,partly in elevation and partly in longitudinal section, of the breechportion of a drop-down gun in whichthe ejector is operated by aroll-over hammer in the fore-end directly actuated by a tripping-rod;and Fig. 2 is an under side view of the same. Fig. 3 is a section onthe-line 3 3, Fig. 2, certain parts being removed; and Fig. 4 is a viewsimilar to Fig. 1, but showing the breech open and the other parts ofthe mechanism in a corresponding position.' Fig. 5 is a view similar toFig. 2, but showing the position of the parts when the breech is open.Figs. 6, 7, 8, and 9 are views hereinafter described of our improvedspring-lever andof the trippingrod. Fig. 10 is an elevation, partly insection, showing the application of our invention to a gun in which theejector is operated by means of a hammer normally held by a scar or likelever. Fig. 11 is a view similar to Fig. 10, showing the position of theparts when the breech is opened.

Similar letters of reference indicate corresponding parts in the severalfigures.

ct C6 are the barrels.

b is the fore-end strap, 0 the frame of the gun and d the lump of thebarrels, which lump when the gun is closed enters a correspondinglyshaped slot or aperture d in the frame.

e is the extractor rod,f the hammer or cam by means of which the rod isoperated and g the tripping rod sliding in the frame and serving toactuate or cause the release of the cam or hammer f, all of which partsare of ordinary construction and require no further description.

h is our lockinglever which is pivoted atz' on the under side of theframe 0 and pro vided with two lugs or projectionsj, at its ends theformer of which two projections is designed to enter the notch Z whichwe form in tho tripping rod while the latter k is designed, when thebarrels are dropped down and the lump d consequently withdrawn from theaperture d to project into the saidaperture. The construction of thislever It will be most clearly understood by reference to Figs. 6, 7 and8 which are respectively a side view, an under side view and an end viewof the said lever; and the arrangement of the notch Z in the rod Q willbe clearly understood by reference to Fig. 9 which is an elevation ofthe tripping rodg detached. It will be seen by reference to thesefigures that the locking lever it consists in this instance of a flatbar having at one end the upturned projection for engaging the trip rodg and at the other end the upturned projection 70 having a beveled orcam surface for engaging the barrel lump.

m is a spring which acts to move the trip ping rod 9 so as to draw itsprojecting end into the frame of the gun when the gun is closed and n isaspring which normally tends to move the lever It so that its endj shallongage with the notch l in the tripping rod g.

In the arrangement of our invention shown in Figs. 1 and 2 the trippingrod g, which acts directly upon the spring operated roll over hammerftothrow it over the dead center so that the usual spring will act upon itto operate the ejector, has one end reduced in diameter and the spring mplaced upon this reduced portion in such a manner that the said springnormally tends to hold the rear end of the tripping rod within the frameagainst a pin or projection 0 upon the hammer 0', while in thearrangement of our invention shown in Figs. 10 and 11, wherein thetripping rod operates to move the sear or like lever which holds thehammer f, the spring m is represented as engaging with a notch in thetripping rod in such a manner as to tend to normally draw the saidtripping rod within the frame of the gun and hold aprojection 13 uponthe tripping rod in contact with the hammer 0'.

The operation of the mechanism hereinbefore described is as follows: 50long as the hammer 0' is in the cocked position the tripping rod g iswholly within the frame of the gun and our locking lever h is in theposition shown in Fig. 2, that is to say, in a position in which the endj is out of engagement with the notch Z in the tripping rod. If now thegun is fired the hammer 0 causes the tripping rod to be projectedforward so that its end projects beyond the end of the frame and so thatthe notch Z in the tripping rod g is brought opposite to the endjof thelever 72.

When in opening the gun, for the purpose of ejecting the empty cartridgecases; the lump d commences to move out of the aperture d the support istaken away from the end it of the lever h whereby the latter is allowed,under the action of its spring n to move so that its endj engages withthe notch Z in the tripping rod g as shown in Figs. 4eand 5, the otherend projecting into the aperture d. The tripping rod is then firmly heldagainst longitudinal movement so that it will operate the ejecting camor hammer f notwithstanding the fact that the complete opening of thegun causes the cooking of the hammer or striker 0 in a well knownmanner. \Vhen the gun is again closed the lump d by pressing against theend 7c of the lever it moves the latter to draw the endj out ofengagement with the notch Z whereby the tripping rod is free to moveback, under the action of its'spring, into the position shown in Fig.1in which it will be again moved forward by the hammer 0' when the gun isagain discharged.

In order that the end is of the lever h which projects into the apertured shall not form an obstruction to the proper closing, the surface ofthe said projection is against which the lump (1 first impinges isbeveled as before stated and as shown clearly in Figs. 3 and 8.

The operation of the arrangement shown in Figs. 10 and 11 is the same asthat hereinbefore described except that the tripping rod instead ofoperating directly upon the roll over hammer operates against the searor like lever which releases the hammerf.

Having now particularly described and as certained the nature of oursaid invention and in what manner the same is to be performed, wedeclare that what we claim is- 1. In a drop down gun, the combinationwith the ejector andv ejector operating mechanism, of a trip rodoperatively connected with the hammer and adapted to be forced intooperative relation with the ejector operating mechanism, by the fallingof the hammer, and a locking lever for locking said trip rod inoperative position when the gun is opened, substantially as described.

2. In a drop down gun, the combination with the ejector and ejectoroperating mechanism, of a trip rod operatively connected with the hammerand adapted to be forced into operative relation with the ejectoroperating mechanism, by the falling of the hammer, and a locking lever,having a part for engaging and locking said trip rod in operativeposition when the gun is opened, and a part in position to be engaged bythe barrel lump when the gun is closed, substantially as described.

3. In a drop down gun, the combination with the ejector and ejectoroperating mechanism, of a trip rod operatively connected with thehammer, and adapted to be forced into operative relation with theejector operating mechanism, by the falling o[ the hamnier, a spring fornormally holding said trip rod out of operative position, and a pivotedlocking lever having a part for engaging and locking said trip rod inoperative position when the gun is opened, and a part adapted to beengaged by the barrel lump to disengage said lever from said trip rod,substantially as described.

4. In drop down guns in which the empty cartridge cases are ejected bymeans of an extractor operated by a hammer the. movements of which areproduced by the end of a tripping rod projecting out of the body of thegun, the combination with the said tripping rod of a lever adapted toengage at one end with the tripping rod and at the other end to beoperated by the contact therewith of the lump upon the barrels, the saidlever having arranged in conjunction with it a spring which tends tocause the said lever to engage with the tripping rod, substantially asdescribed and for the purpose "set forth.
